Description

Technical Field

[0001] The present invention relates to the technical field of highway charging, and in particular to a highway mobile charging drive system. Background Art

[0002] With the popularity of electric vehicles, mobile charging technology is also developing to meet market demand. Highway mobile charging is to provide electric vehicles with power through wireless power supply equipment on the road, thereby solving the problem of electric vehicles running out of power during driving. Mobile charging pile technology is also constantly improving, using advanced lithium battery technology and intelligent sensing and automatic docking technology to provide convenient charging services for electric vehicles.

[0003] In the use of wireless power supply technology, an electromagnetic field is formed by installing wireless power supply equipment on the road, such as charging coils or metal plates. When electric vehicles travel on these devices, the receiving device at the bottom of the vehicle interacts with the electromagnetic field to charge the car battery. This method realizes wireless charging of electric vehicles while driving. On the other hand, mobile charging piles automatically connect with electric vehicles through intelligent sensing and start supplying power, providing a fast and convenient charging solution for electric vehicles.

[0004] Although highway mobile charging technology shows great potential, the following technical pain points still exist: the energy loss of wireless power supply technology is relatively high, especially when passing through materials such as tire rubber, which reduces the charging efficiency and increases the cost; in order to meet the charging needs of automobiles, highway metal plates require a voltage of up to 50,000 volts, which brings safety hazards; although mobile charging piles are convenient, their distribution and coverage are still limited, and are affected by problems such as the occupation of oil trucks.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The technical solutions provided by the embodiments of the present invention are described in detail below in conjunction with the drawings.

[0054] In order to better understand the purpose of the present invention, the present invention is described in further detail below.

[0055] See also Figures 1 to 4 The present invention provides a mobile charging driving system for highways, including: a server end, a mobile charging device end, a background control end, and a vehicle end. The server end establishes a communication connection with the mobile charging device end, the background control end, and the vehicle end. The server end processes and analyzes data with the mobile charging device end, the background control end, and the vehicle end, generates a mobile charging device movement instruction and a vehicle movement instruction, sends the mobile charging device movement instruction to the mobile charging device end, and sends the vehicle movement instruction to the vehicle end. The server end includes:

[0056] A data acquisition unit, which acquires the charging demand information of highway vehicles and the operating data of mobile charging equipment, performs data detection on the acquired charging demand information of highway vehicles and the operating data of mobile charging equipment, and outputs the detected qualified data as usable data for highway mobile charging;

[0057] Data acquisition unit workflow:

[0058] Information request and collection: The data acquisition unit first receives charging demand information from the vehicle, such as vehicle identification, current location, etc. At the same time, it collects operating data from the mobile charging device, including device location, power reserve, etc.

[0059] Data verification and detection: Verify the received charging demand information and confirm that the mobile charging device is online by sending communication detection information. In addition, the integrity of the data is checked.

[0060] Data processing and output: The verified and cleaned data will be output as usable data for highway mobile charging for subsequent data analysis and route optimization.

[0061] To ensure accurate data transmission, a clear communication protocol will be defined to regulate data transmission between the vehicle, mobile charging device and server. Advanced encryption technology is used to ensure security during data transmission and prevent data leakage or tampering. To increase data access speed, a data cache mechanism will be set up. At the same time, to prevent data loss, data backup will be performed regularly.

[0062] The data analysis unit substitutes the available data of mobile charging on the highway into a preset digital twin model to obtain a first digital twin image, the first digital twin image includes an image of a location of a mobile charging device and an image of a vehicle traveling on the highway with a charging demand, determines a location available for charging of the vehicle according to the location information of the vehicle traveling on the highway with a charging demand, collects image data of an area available for charging of the vehicle, substitutes the image data of the area available for charging of the vehicle into the preset digital twin model to obtain a second digital twin image, fuses the first digital twin image with the second digital twin image to obtain a charging site simulation image, the charging site simulation image includes an image of a mobile charging device, an image of an area available for charging, and an image of the vehicle traveling;

[0063] Data analysis unit workflow:

[0064] Data substitution and generation of the first digital twin image: The data analysis unit will first substitute the available data of highway mobile charging into the preset digital twin model to generate a first digital twin image including the mobile charging equipment and the location of vehicles with charging needs.

[0065] Determine charging location and collect image data: Based on the vehicle's location information, the data analysis unit will determine the specific locations that can be used to charge the vehicle and collect image data at these locations.

[0066] Generation of the second digital twin image: The collected image data will be substituted into the digital twin model again to generate a second digital twin image that focuses on the detailed environment and conditions of the charging location.

[0067] Data fusion and generation of charging site simulation images: Finally, the data analysis unit will fuse the first and second digital twin images to generate a comprehensive charging site simulation image that shows the mobile charging equipment, the area available for charging, and the vehicle driving conditions.

[0068] The construction of the digital twin model needs to ensure the accuracy and real-time performance of the model in order to generate high-quality digital twin images. Image processing technology is used to ensure that the first and second digital twin images can be accurately aligned and superimposed to generate a realistic charging site simulation image. Through precise algorithms and data analysis, the best charging location is determined to meet the charging needs of the vehicle.

[0069] A path optimization unit determines, based on a simulated image of the charging site, a location available for parking the vehicle in an area where the vehicle can be charged, receives real-time location information of a mobile charging device, substitutes the real-time location information of the mobile charging device and the location available for parking the vehicle into a preset path model, obtains a moving path of the mobile charging device and a moving path of the vehicle, substitutes the moving path of the mobile charging device and the moving path of the vehicle into a preset digital twin model, and obtains a simulated charging path image;

[0070] The path optimization unit first extracts features from the simulated image of the charging site to obtain information about the open space in the image. Through image recognition technology, it identifies the sign information in the open space, such as parking space signs and no parking signs. It matches these sign information with the preset no parking sign knowledge base to determine the specific location where parking is allowed. Through coordinate conversion, the location points in the image are converted into coordinates of the map standard coordinate system, so as to accurately locate the location where parking is allowed.

[0071] The path optimization unit receives the current location information of the mobile charging device in real time to ensure the real-time and accuracy of path planning. The real-time location of the mobile charging device and the location where parking is allowed are substituted into the preset path model to calculate the optimal movement path. The calculated movement path is substituted into the digital twin model to generate a simulated charging path image, including the movement path of the mobile charging device and the vehicle.

[0072] The driving unit loads the simulated mobile charging device moving path in the simulated charging path image into the mobile charging device, receives in real time the image data collected by the mobile charging device during the movement of the simulated mobile charging device moving path, obtains a real-time mobile device field of view image, compares the real-time mobile device field of view image with the simulated charging path image, and if the comparison results are consistent, sets the operating parameters of the mobile charging device during the execution of the simulated mobile charging device moving path as the mobile charging device driving parameters;

[0073] The drive unit first accurately extracts the moving path of the simulated mobile charging device from the simulated charging path image. Through a secure and stable communication connection, the extracted moving path instruction is sent to the mobile charging device. After the mobile charging device receives the instruction, its built-in system interprets the path information and instructs the device to move along the path.

[0074] During the movement, the high-definition image acquisition system on the mobile charging device will continuously capture real-time images of the surroundings. The image data is transmitted back to the server in real time through an efficient communication connection, received and processed by the drive unit, and a real-time image of the mobile device's field of view is generated.

[0075] The drive unit carefully compares the real-time generated image of the mobile device's field of view with the original simulated charging path image. The comparison process uses advanced image processing technology, including feature point extraction and image registration, to ensure the consistency of the two.

[0076] If the comparison results show that the real-time image is highly consistent with the simulated image, it means that the mobile charging device is moving steadily along the predetermined path. In this case, the drive unit will record and analyze the current operating parameters of the mobile charging device (speed, acceleration, direction, etc.) and set these parameters as the driving parameters of the mobile charging device to ensure that it continues to move steadily along the predetermined path.

[0077] If there is a deviation in the comparison results, the drive unit will immediately identify the abnormal situation and initiate an emergency response, such as adjusting the direction or speed of the mobile charging device or even replanning the route to ensure the safety and efficiency of the system.

[0078] The mobile unit generates a mobile charging device movement instruction according to the mobile charging device driving parameters, and sets the path from the simulated vehicle to the vehicle parking position in the simulated charging path image as the vehicle movement instruction.

[0079] The mobile unit first receives the driving parameters of the mobile charging device from the driving unit. The driving parameters include key information such as moving speed, direction, and target position.

[0080] Once received, the mobile unit parses these parameters in detail to ensure an accurate understanding of how the mobile charging device should move.

[0081] Based on the parsed driving parameters, the mobile unit will generate specific movement instructions, which cover operations such as starting, stopping, turning, accelerating and decelerating, aiming to guide the mobile charging device to move precisely according to the predetermined path and parameters.

[0082] The mobile unit will accurately extract the complete path information of the simulated vehicle from the current position to the scheduled parking position from the simulated charging path image, including key data such as the specific coordinates of the path and the estimated arrival time.

[0083] Based on the extracted path information, the mobile unit further generates vehicle movement instructions. These instructions describe in detail how the vehicle should move safely and efficiently from its current location to a predetermined parking location for charging, including specific path coordinates, recommended driving speeds, necessary turn instructions, etc.

[0084] When vehicle movement instructions are generated, the mobile unit will immediately send these instructions to the vehicle to ensure that the vehicle can move accurately along the predetermined path.

[0085] At the same time, the mobile unit also needs to synchronize data with the mobile charging device and the vehicle in real time to ensure the accuracy and timeliness of the instructions.

[0086] A charging unit, when the mobile charging device moves to a designated position according to a mobile charging device movement instruction, and the vehicle moves to the designated position according to the vehicle movement instruction, the charging unit at the mobile charging device end charges the vehicle;

[0087] The power supply unit establishes a power supply connection with the contact network. The power supply unit receives power supply demand information, matches the preset power supply mode according to the power supply demand information, and supplies power to the charging unit according to the matching result. The preset power supply modes include a first power supply mode, a second power supply mode and a third power supply mode. The first power supply mode is set to a contact network power supply mode with a positive pole of 1500 volts and a negative pole of 0 volts. The second power supply mode is set to a positive pole and a negative pole of 750 volts. The first power supply mode and the second power supply mode both adopt the method of converting the AC power output from the power point into DC power and then supplying it to the charging device. The third power supply mode is set to step down the high-voltage AC power output from the power point through a transformer and convert it into DC power, and then convert the DC power into AC power through an inverter and supply it to the charging device.

[0088] The first power supply method: the contact network with positive pole 1500 and negative pole 0, and the design method of collecting AC and DC;

[0089] The first power supply method works by using a contact network with a positive pole of 1500 volts and a negative pole of 0 volts. In this system, "AC-DC-DC" may refer to the fact that the AC power output from the power point is first converted into DC power, and then directly supplied to the equipment or electric vehicles on the road, eliminating the intermediate energy conversion link and improving the efficiency of power use. The contact network is a conductive network responsible for transmitting electrical energy.

[0090] The first power supply mode has the following characteristics: the high voltage positive pole and zero potential negative pole may help improve the efficiency of power transmission. At the same time, by reducing the power conversion link, energy loss is reduced.

[0091] The second power supply method: positive electrode 750, negative electrode 750, collecting AC-DC design;

[0092] The working principle of the second power supply method: In this method, both the positive and negative poles are set to 750 volts. Similar to the first method, the AC power output from the power point is converted into DC power and then directly supplied for use. The "AC to DC" conversion process here is the same as the first method.

[0093] The second power supply mode has the following characteristics: the symmetrical positive and negative voltage settings are adopted, which may help to stabilize the transmission of electric energy. At the same time, unnecessary electric energy conversion is omitted, thus improving efficiency.

[0094] The third power supply method collects the design method of AC, DC and AC;

[0095] The working principle of the third power supply method is: the high-voltage AC power (such as 10 kV or 35 kV) output by the power point is first stepped down and converted into DC power through a transformer, and then the DC power is converted into AC power through an inverter to obtain 2000 volts AC power for use.

[0096] The third power supply mode has the following characteristics: it can flexibly adjust the output voltage and current to meet the needs of different devices. At the same time, through the inverter technology, it can more effectively use the electric energy and reduce the loss. However, the equipment cost of this mode may be higher and it requires more conversion links.

[0097] In general, the three power supply methods are suitable for different scenarios and needs. In practical applications, you can choose the appropriate power supply method according to the specific situation.

[0098] Specifically, the data acquisition unit for a mobile charging drive system on a highway provided by the present invention includes:

[0099] In step S101, the identity of the vehicle that needs to be charged on the highway is determined according to the charging demand information of the highway vehicle, and charging verification information is sent to the vehicle that needs to be charged on the highway. The charging verification information includes charging and not charging. If the vehicle feedback information is charging, the vehicle corresponding to the vehicle feedback information is determined as a real vehicle that needs to be charged;

[0100] In step S102, communication detection information is sent to the mobile charging device, and if information feedback from the mobile charging device is obtained, the mobile charging device corresponding to the information feedback is set as an online mobile charging device;

[0102] In step S104, the information of the vehicle and the mobile charging device corresponding to the data integrity loss warning is replaced, and the replaced information is the data generated by the mobile charging device closest to the mobile charging device and the data generated by the vehicle closest to the mobile vehicle.

[0126] Solve the safety risks of wireless charging: Data-driven precise docking: Through the data acquisition unit, the charging demand information of road vehicles is collected and analyzed in real time to ensure that mobile charging equipment can provide charging services for electric vehicles at a safe and appropriate time and place, avoiding electromagnetic interference and safety hazards caused by wireless charging.

[0127] Safety considerations for route optimization: The route optimization unit not only considers charging efficiency and convenience, but also road safety factors, such as avoiding charging operations in areas with heavy traffic or frequent accidents, thereby reducing safety risks.

[0128] Solve the problem of limited distribution and coverage of mobile charging piles: Dynamic deployment and optimization: Through the comprehensive calculation of the data analysis unit and the path optimization unit, the system can dynamically deploy mobile charging equipment to ensure that they can provide services when and where they are most needed, thus making up for the uneven distribution and limited coverage of fixed charging piles.

[0133] The specific implementation process of the present invention is as follows:

[0134] System deployment and initialization: deploy the server, mobile charging device, backend control, and vehicle to ensure that each end can communicate with each other through the network. Configure the data acquisition unit, data analysis unit, path optimization unit, drive unit, and mobile unit on the server to ensure that each unit can work together. Initialize the mobile charging device, including device location positioning, battery status detection, communication device status detection, etc., to ensure that the device can work normally and access the system.

[0135] Data acquisition and processing: The data acquisition unit receives real-time charging demand information sent by highway vehicles through the vehicle end, including vehicle location, battery capacity, estimated charging time, etc. At the same time, the data acquisition unit also receives device operation data sent by the mobile charging device end, including device location, remaining battery power, device status, etc. The received data is pre-processed and tested to ensure the accuracy and validity of the data. The qualified data is used as usable data for highway mobile charging and output to the data analysis unit.

[0136] Data analysis and path planning: The data analysis unit substitutes the available data of highway mobile charging into the preset digital twin model to generate a first digital twin image, showing the location images of mobile charging equipment and vehicles with charging needs. According to the location information of the vehicle, determine the location that can be used to provide charging for the vehicle. Collect the image data of these locations and substitute them into the digital twin model to generate a second digital twin image. The first digital twin image and the second digital twin image are data-fused to obtain a simulated image of the charging site, showing the mobile charging equipment, the area available for charging, and the vehicle driving image. The path optimization unit determines the location that can be used for vehicle parking based on the simulated image of the charging site. Receive the real-time location information of the mobile charging device, and substitute it and the location that can be used for vehicle parking into the preset path model to calculate the moving path of the mobile charging device and the vehicle.

[0137] The drive and movement instructions are generated, and the calculated movement path is substituted into the digital twin model to generate a simulated charging path image. The drive unit substitutes the simulated mobile charging device movement path in the simulated charging path image into the mobile charging device, and receives the image data collected during the movement of the device in real time, and compares it with the simulated charging path image. If the comparison results are consistent, the operating parameters of the mobile charging device during the execution of the simulated mobile charging device movement path are set as the mobile charging device driving parameters. The mobile unit generates a mobile charging device movement instruction based on the mobile charging device driving parameters. At the same time, the path from the simulated vehicle to the vehicle parking position in the simulated charging path image is set as the vehicle movement instruction.

[0138] Instruction execution and monitoring: The mobile charging device and the vehicle receive and execute the corresponding movement instructions, start moving and prepare for charging operations. The server monitors the movement status of the mobile charging device and the vehicle in real time to ensure that they move according to the predetermined path and instructions. When the mobile charging device successfully docks with the vehicle and starts charging, the server records the relevant data of the charging process, such as charging time, charging amount, etc. After charging is completed, the server generates a charging report and sends it to the background control end for subsequent processing and analysis.

[0139] Through the above implementation modes, the present invention can realize efficient, safe and convenient mobile charging on roads, and solve the problems of potential safety hazards of wireless charging on roads and limited distribution and coverage of mobile charging piles.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations, and the above-described embodiments of the present invention do not constitute a limitation on the scope of protection of the present invention.
